NASA | The Challenge to Fix Hubble's Best Survey Camera

The video discusses a shuttle mission to service the Hubble Space Telescope, focusing on the repair of the Advanced Camera for Surveys (ACS). The ACS experienced a power supply failure, prompting a rapid repair effort. The video details the challenges faced by astronauts working in space, including the development of special tools and techniques. The repair is crucial for continuing astronomical research, as ACS and the Widefield Camera 3 provide complementary capabilities.

What was the primary function of the Advanced Camera for Surveys (ACS) on the Hubble Space Telescope?

• To map the distribution of dark matter in space

• To capture images of Earth's weather patterns

• To monitor solar flares

• To study the surface of Mars

What was the main issue that led to the failure of the ACS?

• A software glitch

• A short circuit in the power supply

• A communication error with ground control

• A mechanical failure in the lens

What was the approach taken to fix the ACS power supply issue?

• Replacing the entire ACS unit

• Switching to a backup power supply

• Developing a rapid repair solution

• Installing a new camera system

What was one of the main challenges faced by astronauts during the ACS repair?

• Working in bulky space suits in confined spaces

• Limited visibility in space

• Lack of oxygen supply

• Communication delays with mission control

How did the team ensure that the repair could be performed by astronauts in space?

• By designing special tools and techniques

• By using robotic arms for the repair

• By training astronauts in underwater simulations

• By conducting repairs remotely from Earth

Why is it important to repair the ACS alongside the Wide Field Camera 3?

• To improve communication with ground control

• To increase the lifespan of the Hubble Space Telescope

• To provide a full set of capabilities for astronomical observations

• To reduce the cost of future space missions

What percentage of time will astronomers use the combination of Wide Field Camera 3 and ACS after the servicing mission?

• 70%

• 80%

• 60%

• 50%
